Arm && Interventions

Group	Intervention	Description
High-flow nasal oxygen during sleep endoscopy	High-flow nasal oxygen	High-flow nasal oxygen will be applied to the patients through nasal openings using Optiflow system during sleep endoscopy. Pulse oximetry will be monitored continuously. Otorhinolaryngologist will observe the degree of upper airway obstruction during sleep endoscopy.
Low-flow nasal oxygen during sleep endoscopy	Low-flow nasal oxygen	Low-flow nasal oxygen will be applied to the patients through nasal openings using conventional nasal cannula during sleep endoscopy. Pulse oximetry will be monitored continuously. Otorhinolaryngologist will observe the degree of upper airway obstruction during sleep endoscopy.

Primary Outcome Measures

Name	Time	Method
oxygen saturation value	For 15 minutes during sleep endoscopy. At Day 0.	Pulse oximetry will be monitored continuously during sleep endoscopy. Oxygen saturation value will be recorded during the procedure.
